PROCESS OF MAKING LAClNG-STUDS.

SPECIFICATION forming part of Letters Patent No. 256,116, dated April11, 1882. Application filed December 19,1881. (No model.)

To all whom it may concern:

Be it known that I, MELLEN BRAY, of New- I ton, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulProcess of Forming Lacing-Studs, of which the following, taken inconnection with the accompanying drawings, is a specification.

My invention relates to a process of forming lacing studs or hooks fromwire of a diameter about equal to the diameter of the shank of saidstud; and it consists in cutting from said wire a cylinder of suitablelength, submitting said blank to the action of dies to bend one portionthereof at right angles to the other portion and cmboss or swage thesame, so as to form a shoulder around the shank and give shape to theneck and outer head projecting radially from one side of said. shank,bending said neck to bring the outer head over the shank, and thendrilling out the center of the shank to form a tube.

Figure 1 of the drawings is an elevation of a cylinder of iron wire fromwhich a lacingstnd is to be formed. Figs. 2 and 3 are respectively aplan and side elevation of the same piece of metal after it has beensubjected to the action of the bending and swaging dies. Figs. 4 and 5are respectively an inverted plan and a longitudinal section of the sameafter being subjected to the action of the trimming-dies. Fig. 6 is aside elevation after the neck is bent, and Fig. 7 is a vertical sectionof the same after the shank has been drilled.

In carrying out my improved process I first cut from a wire of adiameter corresponding to the desired diameter of the shank to be formeda blank, A, of the proper length, as shown in b, the collar or shoulderwhich bears upon the material when the stud is set; 0, the neck; d, theouter or button head, and c the fin or surplus metal thrown out betweenthe swagingdies. This surplus metal or fin e is then cut away by a pairof suitably-shaped dies, and the neck 0 is bent so as to bring thebutton-head (1 directly over the shank a and inner head or collar, 1),as shown in Fig. 6, after which the shank a is drilled out to form atube, as shown in Fig. 7, when the stud is complete, except tumbling andcoating its exterior with a suitable covering of japan, lacquer, tin, orother metal, which latter operations constitute no part of my presentinvention.

By this process I am enabled to produce lacin g-studs havingall theadvantages ofstrength and neatness of finish of the studs now formed bycutting the neck and outer head from a solid piece of metal withoutbending, and at a very material saving in cost.

(hat I claim as new, and desire to secure by Letters Patent of theUnited States, is

Theprocess of forming lacing studs or hooks which consists in cutting acylindrical blank from a wire of a diameter about equal to the desireddiameter of the shank of the stud or hook to be made, bending oneportion of said blank at right angles to the other portion, and

embossing or swaging said bent-over portion by means of suitable dies togive contour to the parts which are to constitute the neck and the outeror button head, bending the neck to bring the button-head over the shankand inner head, and then drilling out the center of the shank,substantially as and for the purposes described.

Executcd at Boston, Massach usct'ts, this 16th day of December, A. D.1881.

MELLEN BRAY.
